ANH has a lot of “show, don’t tell” problems in regards to Luke’s piloting ability up until the trench run. I’m surprised nobody’s rendered a short sequence of the T16 Skyhopper zooming around Beggar’s Canyon to insert immediately before the theatrical introduction to Luke.
Nowadays if you released ANH a lot of crusty nerds would complain up and down about his piloting ability coming out of nowhere. But the truth is sometimes those details don’t need to be explained in exhausting detail. People can roll with a lot if a film is easy and breezy.
